1N4740A-TAP

Overview

The Vishay 1N4740A-TAP is a silicon planar power Zener diode in the DO-41 (DO-204AL) through-hole package. It provides a nominal Zener voltage of 10 V with a standard tolerance of ±5 %. The device dissipates up to 1.3 W at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 10 μA, a dynamic impedance of 7 Ω, and a test current of 25 mA.

Feature Summary

• Designed for use in stabilizing and clipping circuits requiring high power ratings
• Utilizes silicon planar technology for robust performance
• Features a standard Zener voltage tolerance of ±5 %

Applications

• Voltage stabilization
• Clipping circuits

Procurement Notes

Verify that the ordering suffix '-TAP' corresponds to the specific ammopack packaging configuration containing 5000 units per pack. Confirm compliance with material categorization standards by referencing the official Vishay documentation. Ensure the component meets the required environmental specifications before final procurement decisions are made.

Selection Notes

Select this component when a 10 V reference with ±5 % accuracy is required in a through-hole design. The 1.3 W power dissipation capability supports applications needing higher thermal handling than standard low-power diodes. Verify that the operating ambient temperature remains within the specified limits to maintain safe junction temperatures during continuous operation.

Part Context

This part belongs to the 1N4728A to 1N4761A series of silicon planar power Zener diodes manufactured by Vishay Semiconductors. The series covers a wide Zener voltage range from 3.3 V to 75 V. The 1N4740A variant specifically targets the 10 V segment of this extensive product line.

Replacement Considerations

Cross-reference other manufacturers offering the 1N4740A designation in the DO-41 package. Verify that alternative sources match the 1.3 W power rating, 10 V nominal voltage, and ±5 % tolerance specifications exactly.
